CRB600H high-strength steel bar is a common material in building construction. This kind of steel bar has the characteristics of good ductility, high strength and convenient use. The application field is also very extensive, not only in civil commercial residential buildings, shopping malls, schools, hospitals and other buildings, but also in the construction of expressway and high-speed rail. When building high-speed rail, CRB600H high-strength steel bars will be used for sleepers and track beds, because this kind of steel bars are stronger than ordinary steel bars in strength, tensile strength and ductility. When used for laying rails, it can prolong the service life of rails and improve the comprehensive level of railway engineering construction.
